Let me do the honours.
No offense to Spirictum of course, he surely wasn't the only one who grossly misjugded what my Stability would look like in the twelve-hundreds. Shame Stability checks can't trigger positive events when you have a good score.
I'm not thoroughly checking your updates, but I'm still pretty sure your stability isn't growing just because the game is simply going forward. That doesn't mean I thought your stability wouldn't be ok by the twelve-hundreds.
Making a deeper analysis on your stability:
- Your domestic stability seems normal for this time of the game. You have religious unity, surplus happiness in several cities with more then the average pop/city ratio and a good civic combo (this last one is really easy by this era);
- Your Economy Stability is impressive, congratulations which I'd suppose is entirely related to the Great Lighthouse. Your economic Growth factor is normal, and will suffer fluctuations now and then, so be careful with plagues;
- Your Foreign Stability is the most impressive of all. You still don't have any Vassals, no Defensive Pacts, so this is completely tied to OBs with most civs you know, and more importantly with civs that have a different State Religion. May I presume that you purposedly keep units on far away places so you can keep contact with civs? Now this rises some questions, I'll go there to the DoC forums ask about them.
Now this means something really important:
- Civic Combos start to become a problem in the transition started in the renaissance. When you can finally adopt more modern civics this will become ok again;
- The Great Lighthouse will eventually become obsolete, and then I believe managing to get that high Trade Stability bonus will become tougher;
- Every plague will temporarily crush your Economic Growth Stability factor, so you'll have to be careful when these happen;
If you manage these well you'll survive until the end. OTOH your inflation is becoming a more serious problem. I'm not sure in 1.12, but in the revision we're playing on the Caliphate there is a factor for inflation that, if present on 1.12, must have been triggered for you without your notice. It's a population trigger to inflation. In our case, if any civ has more then 120 population on the Medieval Era, a factor enters into motion which accelerates the inflation growth. For old civs like ours (Egypt and Arabia) it's a really important factor to care about.
